If you do have them now, do you have them with more than 50lbs? Because not training weighted will likely cause some detraining by the time you have your test. So, it's not that BW will compromise your ability to do weighted - the concern is that without training weighted with a pronated grip at all, BW won't be enough of a stimulus to develop or maintain the strength needed to do weighted.
